As clear and straightforward as possible
At a first sight, straightforwardness might not seem like basic-principle material, but it is an important aspect of my last self-employment attempt (as explained in communication 2.0) and that's why I have included it anyway.

Although my previous communication wasn't precisely straightforward, I am certainly a clear and direct guy. So, what this new "principle" basically means is that Custom Solvers 2.0 will communicate as I would do in a personal situation.
